Aspose.Cells组件可以不依赖excel来导入导出excel文件：
导入：
[csharp]
public static System.Data.DataTable ReadExcel(String strFileName)
{
Workbook book = new Workbook();
book.Open(strFileName);
Worksheet sheet = book.Worksheets[0];
Cells cells = sheet.Cells;
return cells.ExportDataTableAsString(0, 0, cells.MaxDataRow + 1, cells.MaxDataColumn + 1, true);
}
public static System.Data.DataTable ReadExcel(String strFileName) { Workbook book = new Workbook(); book.Open(strFileName); Worksheet sheet = book.Worksheets[0]; Cells cells = sheet.Cells; return cells.ExportDataTableAsString(0, 0, cells.MaxDataRow + 1, cells.MaxDataColumn + 1, true); }
导出：
[csharp]
private static void Export<T>(IEnumerable<T> data, HttpResponse response)
{
Workbook workbook = new Workbook();
Worksheet sheet = (Worksheet)workbook.Worksheets[0];
PropertyInfo[] ps = typeof(T).GetProperties();
var colIndex = "A";
foreach (var p in ps)
{
sheet.Cells[colIndex + 1].PutValue(p.Name);
int i = 2;
foreach (var d in data)
{
sheet.Cells[colIndex + i].PutValue(p.GetValue(d, null));
i++;
}
colIndex = ((char)(colIndex[0] + 1)).ToString();
}
response.Clear();
response.Buffer = true;
response.Charset = "utf-8";
